Key result
Type:
relative density
Density:
>= 1.44 - <= 1.45 kg/m³
Temp.:
19.4 °C

Duplicate determinations were performed to ensure a reproducibility of less than ± 20 kg/m3 was obtained.

Conclusions:
The density of the test item has been determined to be 1.45 x 103 kg/m3 at 19.4 ± 0.5 °C and a relative density of 1.45.
Executive summary:

The relative density determined using a gas compression pycnometer, designed to be compatible with Method A.3 Relative Density of Commission Regulation (EC) No 440/2008 of 30 May 2008 and Method 109 of the OECD Guidelines for Testing of Chemicals, 02 October 2012 in accordance with GLP. the test item was determined to have a density of 1.45 x 103 kg/m3 at 19.4 ± 0.5 °C and a relative density of 1.45.
